Motion Stereographic Panorama


This demo uses WebGL fragment shaders to map a pixel coordinate to an equirectangular panorama image. It projects a 180° view in motion using the stereographic projection.


The amount of processing time required for applying a non-rectilinear projection in a game is significant, and was seen while creating Blinky, a panoramic mod for Quake. The use of fragment shaders speeds up this process by computing each pixel in parallel on the GPU. This demo demonstrates its speed.
